📱 How Your Phone Rings Instantly The Complete Journey from Call to Ring 1 🤙 Friend Presses Call Your friend dials your number and hits the call button. The mobile network sends out a paging signal targeted specifically to your phone number. 2 📡 Modem Catches Signal Even while your phone appears idle, the modem hardware is constantly listening to signals from nearby mobile towers. It picks up the paging signal like a walkie-talkie. 3 📞 Telephony Services Interpret The telephony service (built into your OS) reads the incoming signal and prepares your phone to handle the call. It's like a translator between the modem and your phone's software. ...

 Have you ever opened Task Manager, noticed a suspicious-looking process, and decided to end it — only to have your system suddenly crash with a Blue Screen of Death (BSOD) and a QR code? That recently happened to me, and I learned a valuable lesson: some processes are absolutely critical to Windows . Here’s a full breakdown of what happened, why it happened, and how it connects to deeper OS concepts like IPC, process synchronization, and critical sections. What Is the Blue Screen of Death (BSOD)? The BSOD appears when Windows encounters a critical system error it cannot recover from . Rather than continuing and risking data corruption or hardware failure, it crashes safely and displays error information. The QR code usually links to  BSOD , where you can learn more about the error. Common causes of BSOD include: Corrupt or missing system files Hardware failure Driver issues Improper memory access Terminating essential processes (like I did) 🔴 Why the BS...

 " In the race of smartphones, iPhones prove that optimization beats brute force every time. " Why Android Phones Have More RAM but iPhones Perform Better In today’s smartphone world, a big question pops up: 👉 " Why do Android phones have 8GB or 12GB RAM, but iPhones with just 4GB or 6GB still feel faster and smoother? " Let’s dive into the real reasons — and trust me, it’s more interesting than you think! 🔥 First, Understand How iPhones Manage RAM iPhones don’t just rely on RAM. They have a secret weapon: super-fast NAND storage . NAND Storage is extremely quick and efficient. It’s not "Not A NAND Device" 😉 — NAND is a special kind of flash memory used in iPhones. NAND storage uses different types of cells: SLC (Single-Level Cell) — fastest and most durable. MLC (Multi-Level Cell) — stores more but a little slower. TLC (Triple-Level Cell) — cheaper, more storage. QLC (Quad-Level Cell) — even more storage, less durabili...

 It’s a common situation—you buy a brand new 32 GB pen drive , plug it into your computer, and boom... it shows only around 29.5 GB. You start wondering, “Where did the rest of the storage go?” Well, don’t worry. This isn’t a mistake or a manufacturing fault. It all comes down to how data storage is measured and how computers interpret it. Let’s break it down in the simplest way possible. What manufacturers use: Decimal (Base 10) Companies that make pen drives and hard drives use the decimal system to define storage. In this system: 1 KB = 1,000 Bytes 1 MB = 1,000 KB 1 GB = 1,000 MB So a 32 GB pen drive actually means it has 32,000,000,000 bytes of space. What computers use: Binary (Base 2) Computers don’t think in decimal. They use the binary system , where: 1 KB = 1,024 Bytes 1 MB = 1,024 KB 1 GB = 1,024 MB So 1 GB in binary = 1,073,741,824 bytes Now, if we divide the 32,000,000,000 bytes by the binary GB value: 32,000,000,000 ÷ 1,073,741,824 = approx. ...
